List of all colors available for PowerShell?

问题

I am searching for a list of all colors I can use in PowerShell. Since we need to provide names and no hexnumbers, it's hard to figure out if a color exists or not, at least if you don't know how :))

For example, as -foregroundcolor

write-host "hello world" -foregroundcolor "red"

回答1:

The console colors are in an enum called [System.ConsoleColor]. You can list all the values using the GetValues static method of [Enum]

[Enum]::GetValues([System.ConsoleColor])

or just

[Enum]::GetValues([ConsoleColor])

Pretty grid

$colors = [enum]::GetValues([System.ConsoleColor])
Foreach ($bgcolor in $colors){
    Foreach ($fgcolor in $colors) { Write-Host "$fgcolor|"  -ForegroundColor $fgcolor -BackgroundColor $bgcolor -NoNewLine }
    Write-Host " on $bgcolor"
}

I've found it useful to preview how the console colors will display with a simple helper function:

function Show-Colors( ) {
  $colors = [Enum]::GetValues( [ConsoleColor] )
  $max = ($colors | foreach { "$_ ".Length } | Measure-Object -Maximum).Maximum
  foreach( $color in $colors ) {
    Write-Host (" {0,2} {1,$max} " -f [int]$color,$color) -NoNewline
    Write-Host "$color" -Foreground $color
  }
}

How about checking the help? Like so, get-help write-host will tell you:

[-BackgroundColor {Black | DarkBlue | DarkGreen | DarkCyan | DarkRed | DarkMagenta | DarkYellow | Gray | DarkGray | Blue | Green | Cyan | Red | Magenta | Yellow | White}]
[-ForegroundColor {Black | DarkBlue | DarkGreen | DarkCyan | DarkRed | DarkMagenta | DarkYellow | Gray | DarkGray | Blue | Green | Cyan | Red | Magenta | Yellow | White}]

Here is an examle of displaying all color combinations of background and foreground colors.

$FGcolors = [enum]::GetValues([System.ConsoleColor])
$BGcolors = [enum]::GetValues([System.ConsoleColor])

Foreach ($FGcolor in $FGcolors)
{
    Foreach ($BGcolor in $BGcolors)
    {
        Write-Host ("Foreground: $FGColor BackGround: $BGColor")  -ForegroundColor $FGcolor -BackgroundColor $BGcolor
    }
}
